如何才能找到一个表单通过单击X按钮或（this.Close（））？

How can I find out if a form is closed by clicking the X button or by (this.Close())?

推荐答案

窗体上有事件型FormClosingEventArgs参数的FormClosing。

the form has the event FormClosing with parameter of type FormClosingEventArgs.

private void Form1_FormClosing( object sender, FormClosingEventArgs e )
{
    if ( e.CloseReason == CloseReason.UserClosing )
    {
        if ( MessageBox.Show( this, "Really?", "Closing...",
             MessageBoxButtons.OKCancel, MessageBoxIcon.Question )
            == DialogResult.Cancel ) e.Cancel = true;
    }
}
